Subject: [dpdk-dev] [PATCH 07/15] net/bnxt: fix L2 context calculation for Thor
Date: Sun, 1 Sep 2019 15:12:11 -0700 [thread overview]
Message-ID: <20190901221213.92149-8-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20190901221213.92149-1-ajit.khaparde@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
On Wh+, number of L2 context supported by FW is the sum of number of
EM flow count and number of L2 context count returned in HWRM_FUNC_QCFG.
This is not true for Thor. Restrict this only for Whitney for now.
Fixes: ff9c0ca47e81176 ("net/bnxt: save the number of EM flow count")
